POCO M7 with 7000 mAh battery: technical analysis and performance

POCO M7 is a new low-cost smartphone in Vietnam, aiming for long-lasting use and smooth experience within its price range. The device stands out with a 7000 mAh battery, 6.9-inch 144Hz screen, Qualcomm Snapdragon 685 processor, IP64 dust and water resistance, 50MP camera and 33W fast charging. The product has two versions: 6GB/128GB priced at 4.59 million VND and 8GB/256GB priced at 5.29 million VND, competing directly with OPPO A3x, Samsung Galaxy A17 LTE, Realme C75x.

Position in the segment and the problem of usage time

At the price range under 5.5 million VND, choices often trade off between performance, screen and battery. POCO M7 chooses a different approach: dramatically increasing the battery capacity to 7000 mAh, while maintaining the experience thanks to the 144Hz screen and Snapdragon 685 platform. The youthful design, four-sided curved back and matte surface limit fingerprints, making the device easy to hold, while the display uses a trendy hole-punch design instead of the waterdrop commonly found on many low-cost devices.

Display, sound, and durability: 6.9-inch 144Hz, Dolby Atmos, IP64

The 6.9-inch FHD+ display provides sharp images, true colors, and wide viewing angles. The maximum refresh rate of 144Hz allows for smooth scrolling and transitions in apps and games. The 9-level adaptive refresh rate system allows the device to automatically adjust to the content, balancing visual effects and power consumption. The device is certified for eye protection by TUV Rheinland and supports Wet Touch 2.0 to receive touch even when the screen is wet.

The sound is enhanced with a dual speaker system that is up to 200% louder than the previous generation, supporting Dolby Atmos for clear and distinct sound when listening to music, watching movies or making video calls. In terms of durability, POCO M7 is IP64 certified for light dust and water splash resistance, along with mechanical tests such as 500,000 power button presses, 28,000 light drops and 3,000 compressions, aiming for reliability in daily use.

Processor and software platform: Snapdragon 685, expandable RAM, HyperOS 2.0

POCO M7 uses Qualcomm Snapdragon 685. Although it is not a new chip, the appearance at a price of less than 5.5 million VND is a significant advantage. The device achieved about 350,000 points on Antutu 10 (according to the information provided), enough to meet the needs of popular applications and games. Two RAM options of 6GB or 8GB come with the ability to expand virtual RAM, making multitasking more flexible in situations where heavy application loading is required.

In terms of software, the device comes pre-installed with HyperOS 2.0 with a friendly interface, integrating many new features and AI utilities, including Gemini assistant to optimize the user experience.

50MP camera system: focusing on basic frames

The dual rear camera cluster includes a 50MP main sensor with f/1.8 aperture for sharp, impressive color images, and a 0.8MP secondary sensor to support expanded shooting styles. The 8MP front camera meets the needs of selfies and video calls at a good level. The device has AI features to enhance photo quality, automatic night mode to improve in low light situations, and a beauty mode to keep portrait photos natural.

7000 mAh battery and charging: duration data from the manufacturer

The 7000 mAh battery is the highlight. According to the manufacturer, the device can be used for more than 2.3 days with basic needs, 46 hours of talk time, 28 hours of video viewing and 29 hours of reading. When the battery is at 1%, thanks to BatteryExtender, the device can still talk for up to 64 minutes or stand by for 10 hours, even in harsh conditions such as low temperatures of -20°C. 33W fast charging shortens the recharge time, while 18W reverse charging turns the phone into a convenient charging source for other devices. Smart Charging 2.0 and Battery Health 4.0 technology optimizes speed when the battery is low while aiming for long-term battery life.

Trade-offs and challenges

• The Snapdragon 685 platform isn't new; the priority is stability and optimization within the price range rather than performance breakthroughs.
• The 0.8 MP secondary sensor is supportive, the camera system focuses on basic shooting needs.
• Competition in the 4-5 million VND segment is fierce with many options from OPPO, Samsung and Realme.
• The 144Hz display requires intelligent power management; POCO M7 solves this problem with 9 adaptive refresh rate levels and accompanying battery saving technologies.

Quick comparison and outlook

Compared to competitors like OPPO A3x, Galaxy A17 LTE and Realme C75x, POCO M7 stands out with a rare combination of features at the same time in its price range: 7000 mAh battery, 144Hz punch-hole display, Dolby Atmos dual speakers and IP64. While many low-cost devices still use waterdrop design, POCO M7 offers a more modern display experience. With a strategy that emphasizes durability and practicality, POCO M7 is suitable for users who need a durable device for daily needs, from communication, entertainment to basic work.
